This is turning out to be an unusually strong week for the Afternoon Play slot. Yesterday's drama, The Confessions (Radio 4), offered a taut, saucy and claustrophobic dynamic between four characters tangled up like fingers in a cat's cradle.

"Yes, it is a bit on the naughty side," one character said of an artwork he was valuing, "but it's nicely done." So, too, was Charlotte Greig's play, set in the art world and featuring a cheery background of sadomasochistic, masochistic and sadistic relationships. These were all reflected in readings from Rousseau's Confessions, with its pithy phrases ("dark and dirty labyrinth") underlining developments between the couples. What distinguished this from many an afternoon play was that you couldn't guess where it was going: it wasn't clear until the very end who was going to be the victor in this classily produced and well-performed battle of wills.

On Woman's Hour (Radio 4), Jenni Eclair discussed keeping long-term relationships going. The most common mistake, suggested Eclair, "is the en suite bathroom. It destroys any vestige of romance." But, continuing on the lavatory theme, she said a partner is better than a dog. "A dog can't grab you that toilet roll when you're stuck," she cackled.
